But his political team apparently believes even that figure is a
conservative estimate.

Michael Cohen, an executive vice president and special counsel to
Trump's organization,
said in a Thursday CNN interview that the Trump real-estate
holdings should probably be valued even more. Trump owns a
network of luxury buildings, hotels, golf clubs, and more.

"I consider myself to be an expert in real estate. I can tell you
that $10 billion number, in my estimation, is low," Cohen
said. "Because I know the value of New York City real estate.
You're talking about the prime properties. You're talking about
Fifth Avenue."

He proceeded to list other locations where Trump owns high-end
properties.

"And let's talk about out of New York. On the Pacific
Ocean. On the Potomac River. You have 1,000 acres in the
middle of Miami, just to name a few. The assets that Donald Trump
has — the locations — are second to none," Cohen continued.

Regardless, Trump says he's worth even more now. The Trump
statement on Wednesday said the $8.7 billion figure was based off
of numbers that were more than a year old.

"Mr. Trump's net worth has increased since the more than one year
old financial statement produced at his presidential
announcement," it said. "Real estate values in New York City, San
Francisco, Miami and many other places where he owns property
have gone up considerably during this period of time. His debt is
a very small percentage of value, and at very low interest rates.
As of this date, Mr. Trump's net worth is in excess of TEN
BILLION DOLLARS."
